How to download iOS 11.4.1 to your iPhone and iPad

10 July 2018

In a nutshell, iPhone users have found that the iOS 11.4 update is drastically reducing their battery life. Camera issues and battery drain problems stemming from iOS 11.4 have been patched in the update.

The Restricted Mode for the USB data connection that runs over the Lightning plug on iPhones and iPads is part of the iOS 11.4.1 updatereleased by Apple a few hours ago. However, Apple had not released the details on its security page at the time of this posting, but expect them to appear sometime soon.

Even if forensic engineers are able to stop the device they're trying to break into from entering USB Restricted Mode, Elcomsoft noted that since iOS 11.4, cracking devices such as Grayshift's GrayKey are limited to just one passcode guess per ten minutes. It's off by default.

At first we thought we would have to wait until iOS 12 this fall to see this feature, but here it is.

However, if you aren't actually happy with the release, and you want to go back to an earlier version of iOS, then be aware that Apple is now only signing iOS 11.4, which means that you will only be able to downgrade to iOS 11.4. The watchOS update notes simply state that 4.3.2 "includes improvements and bug fixes". There's precious little question at this point that iOS 11 has been Apple's most problematic mobile software release in many years. If you have taken the opportunity to upgrade your compatible device to iOS 11.4.1 and immediately regret that decision for one reason or another, then it is possible to downgrade the firmware.
